Another long-legged tachnid?

Been away, just checking emails and see the post 2017-07-24 from Nigel Gilligan. I took this near the Exhibition Centre at Stonehenge and noted the long legs.  I am very inexperienced and may not be looking properly at my photo but is this a Dexiosoma caninum too?

No, not unless it has 7 legs. wink

Try Prosena siberita instead.

Sorry Sabina.....I will stick to microscope and keys Michael !

Attached a pic showing the '7th leg' that Michael refers to. This one is on Siphona geniculata but it shows the general idea.

So the proboscis is very long making up the '7th' leg. Have just found some excellent photos of the Prosena siberita. Many thanks.
